Sawn teak or English source of wood? (3,4)
I believe the answer is:
'source of wood?' is the definition.
'oak tree' can be an answer for 'source' (I have seen 'Source of acorns' mean 'oak tree' so perhaps 'source' could also mean 'oak tree'). I am not certain of the 'of wood?' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for oak tree that I've seen before include "wood source?" , "royal hiding place evidently" , "Source of acorns" , "Product of acorn" , "famous royal hideout" .)
